Answer:
each time it is increasing by twice the on before it
Step-by-step explanation:
The equation of the line graphed below would be D. I can find two points that are easily distinguishable on this graph. (1, 5) and (0, 0). I found the slope by subtracting 0 from 5 giving me -5. Next, I subtracted 0 and 1 giving me -1. This gives me a fraction of -5/-1 which equals to 5.
The band earned $1,200.
1. Subtract the flat fee 1,200-700 =500
2. 500 is what just the band made. Divide that by .16 (16%) to get the total ticket amount... 500 divided by .16 = 3,125
The total ticket amount was $3,125.
This is a simultaneous system of two linear equations with two unknowns, as the number of unknowns equals the number of equations, we can solve it:
y = 5x + 21
y = -7x - 15
we can equate both equations, given the fact that both are equal to y:
y = y
5x + 21 = -7x - <span>15
</span>and solving for x:
5x + 7x = -15 - 21
12x = -36
x = -36/12
x = -3
then we substitute this result in the original equation:
y = 5x + <span>21
</span>y = 5(-3) + <span>21
</span>y = -15 + 21
y = 6
hence the solution is x = -3 and y = 6
Answer:
4 cm
Step-by-step explanation:
Both the area of a square and the area of a rectangle can be found by multiplying length x width. Because all of the sides of a square are equal, you get 64 when you multiply two sides together to find the area.
Since the rectangle has the same area as the square, that means the rectangle's width has to be a number that equals 64 when multiplied by 16.
So, 64/16 equals 4.
